How To Tell If A Casino Slot Machine Is Volatile

The biggest mistake casual gamblers make is ignoring the underlying mathematical engine that drives the slot machine.


A machine's variance tells you whether you are in for a smooth, steady ride or a wild, highly unpredictable rollercoaster.

The Difference Between High and Low Variance

A low volatility slot is designed to pay out small, frequent wins, keeping your bankroll relatively stable over time.


High variance games are incredibly risky; they will drain your budget rapidly, but offer the chance for life-changing payouts.

High volatility slots often feature incredibly complex bonus rounds that are very difficult to triggerLow volatility games are the absolute best choice if you are trying to clear a casino bonus wagering requirementMegaways slots are notoriously high variance, offering thousands of ways to win but long periods of 'dead spins'
Spotting the Signs of High Variance

You can become an expert at spotting high-risk games simply by looking at the payout structure before you spin.


If a game advertises a maximum win of 10,000x or 50,000x your stake, it is undeniably a high volatility slot.
